AI Technical Summary
[0002]汽车内零部件繁多，很多零部件之间需要电线进行电连接，但是，汽车内可用于安装的空间有限，因此，需要将零部件以及线束的位置进行合理安排布局，现有技术中，为了避免线束散乱，通常使用线束支架固定线束的位置，为了车内空间的合理布局，部分线束需要进行一定程度的弯折，其弯折过程中，线束口径越大，产生的反作用力也越大，因此，安装非常不便，且安装稳定性难以保证，现有技术中，线束支架通常是一体成型的，然后在支架上设置扎带孔，通过扎带固定线束，而汽车内空间狭窄，扎带穿过扎带孔再进行固定这种操作方式的难度较大，安装效率较低
[0005]采用上述技术方案，首先，将待固定的线束放置在支架本体上，然后通过扎带穿过扎带槽并绕线束一周扎紧，然后将第一连接块滑入滑动凹槽内，再将第二连接块卡入卡接口中，由于第二连接块上设有两个弹性块，且当弹性块处于初始状态时，两个弹性块之间的间距大于卡接口的直径，当弹性块处于压紧状态时，两个弹性块之间的间距小于或等于卡接口的直径，因此，可以保证第二连接块卡入卡接口后，支架本体与固定基座的相对位置保持稳定，这样可以大大降低对线束的固定难度，提高安装效率。

Description
Technical Field
[0001] This utility model relates to the field of wire harness bracket technology, and in particular to a large-diameter wire harness fixing bracket. Background Technology
[0002] A car has numerous internal components, many of which require electrical connections via wires. However, the space available for installation inside a car is limited. Therefore, the placement of components and wiring harnesses needs to be rationally arranged. In existing technologies, to avoid tangled wiring harnesses, wiring harness brackets are typically used to fix their positions. To achieve a rational layout within the vehicle's space, some wiring harnesses need to be bent to a certain extent. During this bending process, the larger the diameter of the wiring harness, the greater the reaction force generated. Therefore, installation is very inconvenient, and installation stability is difficult to guarantee. In existing technologies, wiring harness brackets are usually integrally molded, and cable tie holes are set on the bracket for securing the wiring harness with cable ties. However, the narrow space inside a car makes it difficult to pass the cable ties through the cable tie holes for securing them, resulting in low installation efficiency. Summary of the Invention
[0003] To address the aforementioned issues, this invention provides a large-diameter wire harness fixing bracket that offers high installation efficiency and effective wire harness fixation.
[0004] The technical solution of this utility model is as follows: A large-diameter wire harness fixing bracket includes a fixing base, a bracket body connected to the fixing base, and a connector connecting the bracket body and the fixing base. The fixing base is provided with a snap-fit interface. The connector includes a first connecting block, a second connecting block connected to the first connecting block, and an elastic block connected to the second connecting block. The first connecting block and the second connecting block are arranged in a T-shape. There are two elastic blocks, which are symmetrically arranged about the central axis of the second connecting block. The elastic blocks have a certain elasticity. When the elastic blocks are in the initial state, the distance between the two elastic blocks is greater than the diameter of the snap-fit interface. When the elastic blocks are in the compressed state, the distance between the two elastic blocks is less than or equal to the diameter of the snap-fit interface. The bottom of the bracket body is provided with a sliding groove and several cable tie slots. The sliding groove is adapted to the shape and size of the first connecting block, and the sliding groove and the cable tie slots are not connected.
[0005] Using the above technical solution, firstly, the wire harness to be fixed is placed on the bracket body. Then, a cable tie is passed through the cable tie groove and wrapped around the wire harness to secure it. Next, the first connecting block is slid into the sliding groove, and then the second connecting block is snapped into the card interface. Since the second connecting block has two elastic blocks, and when the elastic blocks are in the initial state, the distance between the two elastic blocks is greater than the diameter of the card interface, and when the elastic blocks are in the compressed state, the distance between the two elastic blocks is less than or equal to the diameter of the card interface, it can be ensured that the relative position of the bracket body and the fixing base remains stable after the second connecting block is snapped into the card interface. This can greatly reduce the difficulty of fixing the wire harness and improve the installation efficiency.
[0006] A further feature of this invention is that the bracket body is also provided with a fixing plate fixedly connected to the bracket body. The fixing plate is perpendicular to the bracket body. The fixing plate is also provided with a plurality of positioning slots. The number of cable tie slots is the same as the number of positioning slots. The positions of the positioning slots correspond one-to-one with the positions of the cable tie slots.
[0007] By adopting the above technical solution, since the bracket body is also provided with a fixing plate fixedly connected to the bracket body, and the fixing plate is also provided with several positioning grooves, when the cable tie is tied, the cable tie can be passed through the positioning grooves, which plays a role in further limiting the cable tie and preventing the cable tie from sliding relative to the wire harness after being subjected to the reaction force of bending. This improves the fixing effect of the wire harness. In addition, the fixing plate can also support the cable tie, further improving the fixing effect of the wire harness.
[0008] A further feature of this invention is that a reinforcing rib is provided between the fixing plate and the bracket body, and the reinforcing rib is perpendicular to both the fixing plate and the bracket body.
[0009] By adopting the above technical solution, since there are reinforcing ribs between the fixing plate and the bracket body, the connection strength between the fixing plate and the bracket body can be improved, thereby increasing the service life of the device.
[0010] A further feature of this invention is that the bottom of the first connecting block is provided with a first limiting block, and the sliding groove is provided with a second limiting block. The first limiting block and the second limiting block are respectively provided with a first wedge surface and a second wedge surface. The inclinations of the first wedge surface and the second wedge surface are matched. When the first connecting block is completely slid into the sliding groove, the first limiting block and the second limiting block are in a contacting state.
[0011] By adopting the above technical solution, since the bottom of the first connecting block is provided with a first limiting block and the sliding groove is provided with a second limiting block, and when the first connecting block is completely slid into the sliding groove, the first limiting block and the second limiting block are in a contacting state. Therefore, the first connecting block can be prevented from sliding out of the sliding groove, thereby improving the connection stability between the bracket body and the fixed base, and thus improving the fixing effect on the wire harness.

Detailed Implementation
[0017] like Figure 1-4 As shown, a large-diameter wire harness fixing bracket includes a fixing base 1, a bracket body 2 connected to the fixing base 1, and a connector 3 connecting the bracket body 2 and the fixing base 1. The fixing base 1 is provided with a snap-fit interface 4. The connector 3 includes a first connecting block 5, a second connecting block 6 connected to the first connecting block 5, and an elastic block 7 connected to the second connecting block 6. The first connecting block 5 and the second connecting block 6 are arranged in a T-shape. There are two elastic blocks 7, which are symmetrically arranged about the central axis of the second connecting block 6. The elastic blocks 7 have a certain elasticity. When the elastic blocks 7 are in the initial state, the distance between the two elastic blocks 7 is greater than the diameter of the snap-fit interface 4. When the elastic blocks 7 are in the compressed state, the distance between the two elastic blocks 7 is less than or equal to the diameter of the snap-fit interface 4. The bottom of the bracket body 2 is provided with a sliding groove 8 and several cable tie slots 9. The sliding groove 8 is adapted to the shape and size of the first connecting block 5, and the sliding groove 8 and the cable tie slots 9 are not connected.
[0018] First, place the wire harness to be fixed on the bracket body 2. Then, pass a cable tie through the cable tie groove 9 and wrap it around the wire harness to secure it. Next, slide the first connecting block 5 into the sliding groove 8, and then snap the second connecting block 6 into the card interface 4. Since the second connecting block 6 is provided with two elastic blocks 7, and when the elastic blocks 7 are in the initial state, the distance between the two elastic blocks 7 is greater than the diameter of the card interface 4, and when the elastic blocks 7 are in the compressed state, the distance between the two elastic blocks 7 is less than or equal to the diameter of the card interface 4, it can be ensured that the relative position of the bracket body 2 and the fixing base 1 remains stable after the second connecting block 6 is snapped into the card interface 4. This can greatly reduce the difficulty of fixing the wire harness and improve the installation efficiency.
[0019] The bracket body 2 is also provided with a fixing plate 10 fixedly connected to the bracket body 2. The fixing plate 10 is perpendicular to the bracket body 2. The fixing plate 10 is also provided with a plurality of positioning grooves 11. The number of cable tie grooves 9 is the same as the number of positioning grooves 11. The positions of the positioning grooves 11 correspond one-to-one with the positions of the cable tie grooves 9.
[0020] Since the bracket body 2 is also provided with a fixing plate 10 fixedly connected to the bracket body 2, and the fixing plate 10 is also provided with several positioning grooves 11, when the cable tie is tied, the cable tie can be passed through the positioning grooves 11, which plays a role in further limiting the cable tie, preventing the cable tie from sliding relative to the wire harness after being subjected to the reaction force of bending, thereby improving the fixing effect of the wire harness. In addition, the fixing plate 10 can also support the cable tie, further improving the fixing effect of the wire harness.
[0021] A reinforcing rib 12 is provided between the fixing plate 10 and the bracket body 2, and the reinforcing rib 12 is perpendicular to the fixing plate 10 and the bracket body 2 respectively.
[0022] Because a reinforcing rib 12 is provided between the fixing plate 10 and the bracket body 2, the connection strength between the fixing plate 10 and the bracket body 2 can be improved, thereby increasing the service life of the device.
[0023] The first connecting block 5 is provided with a first limiting block 13 at its bottom, and the sliding groove 8 is provided with a second limiting block 14. The first limiting block 13 and the second limiting block 14 are respectively provided with a first wedge surface 15 and a second wedge surface 16. The inclinations of the first wedge surface 15 and the second wedge surface 16 are matched. When the first connecting block 5 is completely slid into the sliding groove 8, the first limiting block 13 and the second limiting block 14 are in a contacting state.
[0024] Since the first connecting block 5 is provided with a first limiting block 13 at the bottom and the sliding groove 8 is provided with a second limiting block 14, and when the first connecting block 5 is completely slid into the sliding groove 8, the first limiting block 13 and the second limiting block 14 are in a contacting state. Therefore, the first connecting block 5 can be prevented from sliding out of the sliding groove 8, thereby improving the connection stability between the bracket body 2 and the fixed base 1, and thus improving the fixing effect on the wire harness.
